Application filed July 9. 1907. Serial No. 382.929,

0 all whom it may concern. 7

Be it known that I, MAX STEINER, a citizen of the United States,residing at Newark, in the county of Essex and State ofNew Jersey, haveinvented certain new and useful Im.- provements in Radiators forAutomobiles; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to figures ofreference marked thereon, which form a part 0 this specification.

Thls invention relates to an improved radiator for the use of coolingdevices in automobiles, and is adapted to provide a radiator throughwhich the air passes, the structure being made up of a series of tubes,and the spaces between the tubes furnishing the channel through whichthe water passes.-

The device consists in supplying the tubes with depressions or recessesin the sides, ,or transversely, these spaces being the means by whichthe water circulates, the other portions of the tubes being adapted tocontact to make tight joints, whereby very little solder is used to jointhem on their ends. Thepreferred form of indenting or recessing thetubes, is to make a freer channel in a horizontal. direction between thetubes, so that the passage of the water from the top to the bottom ofthe radiator, which is common in these radiators, is delayed, and theWater becomes thoroughly cool while passing through the radiator.

The device is illustrated in the accompanyin drawing, in which igure 1is a front view of a portion of a radiator, and Fig. 2 is a side view ofsome of the tubes. Fig. 3 is a top view of one tube, and Fig. 4 is aperspective View of two of the .tubes showing the preferred dispositionof the recesses. Fig. 5 is a face view, and Fig. 6 is a side view ofmodlfied forms of tubes.

. Fig. 7 is a face view showing an arrangement of the tubes in theirrelation to one another, slightly different from that shown in Fig. 1.

The radiator is composed of a suitable casthe tubes 11 are nested withtheir tween them, are made water tight. The air is designed to passthrough these tubes and keep them cool.

' The tubes are preferably made square,

although they may be made six-sided, or any formation that is adaptedfor this purpose, or they might be made circular in cross-section, asshown in Fig. 5. The ends 13 and 14, of the tubes, are made of the samesize so that they abut to form a comparatively tight joint between them,and the to and bottom edges of the tubes are supplie with recesses orchannels 15.and 16 respectively, these being adapted to abut and form afree channel for the passage of water. One of the perpendicular sides ofeach tube 11 is supplied with channels or recesses 17, which arevertically disposed and form a channel for the vertical passa e ofwater. to make the other wall 18, of each tube 11, flat.

The arrangement that is thought to 'bring about the best results, isshown in Fig. 4 where the vertical channel 17, in each tube, fits upagainst the fiat side 18 of the next tube, and this tends to partlyobstruct and make the passage of the water, through the channel 17, ofhalf the capacity of the horizontal I prefer passages formed by thechannels 15 and 16. I

scription, that thewater is checked against a straight flow, and must,of necessity, traverse considerable cooling surface and is of a verymuch lower tem erature after going through the radiator. f desired, Imay make the tubes as shown in Figs. 5 and 6, each tube 19 beingprovided with an end 20 and an end 21, the two ends bein made toregister, or, as shown in Fig. 6, icing placed in reverse position, inwhich case the channels 22 will not register, and will make a staggeredlongitudinalpath for the water, besides the transverse orcircumferential current.

Having thus described my invention, what .I claim is 1. A radlatorcomposed of a series of tubes for the passage of air, the contact of thetubes on the ends being sealed, and the tubes having a series oftransverse channels arranged to connect to form passages for the Water.

2. A radiator composed of a series of tubes for the passage of air, thecontact of the tubes on the ends being sealed, the tubes having a seriesof transverse channels to provide for the horizontal and the verticalpassage of Water between the tubes.

3. A radiator comprising a series of tubes having their contacting endssealed, the tubes having transverse channels arran ed between the ends,a portion of each tube eing flat from end to end to partly obstruct theflow at that point.

4. A radiator comprising a series of tubes, the contacting ends of thetubes being sealed,

the tubes being square in cross-section, and having a series oftransverse channels for the v 6. A radiator comprising a series ofsquare tubes, each tube havlng transverse channels on the top andbottom, and on one of the vertical sides, the vertical side of one tubebeing arranged adjacent to the vertically channeled side of the nexttube.

In testimony, that I claim the foregoing, I have hereunto set my handthis 8th day of July 1907. r I
